permalink shown on edit page page incorrect for sub-pages

[DD32]

The permalink shown on the "edit page" page does not show correctly for sub-pages.

Eg, I've got a page, with the parent "WordPress Plugins"(slug: wordpress-plugins), the permalink shown is:

Permalink: http://dd32.id.au/remove-max-width/ Edit

While in reality, it exists at:

http://dd32.id.au/wordpress-plugins/remove-max-width/

(Note that the "View this page" link does point to the right location.

str_replace()ing the post_name in the page uri may need to change so that parents that have post_name in their text aren't stomped. Only the deepest child should be replaced.

(In [7320]) Only replace the last segment of the uri when generating the sample permalink. Fixes #6068.

The new code works for me in testing a hierarchy with repeated page names.
